    "abstract": "We show, with an example of Na_92, that for jellium metal clusters the\ninterference of fast electron-waves emitted from equivalent sites on the\ncluster edge produces monochromatic oscillations in all photoionization\nobservables as a function of the photoelectron momentum; the effect is\nequivalent to the usual dispersion phenomenon. In dealing with formalisms, a\nserious consequence of the inadequacy of self-interaction corrected local\ndensity-functional theory in correctly accounting for the exchange interaction\nis identified. We also briefly discuss the influence of the ionicity of the\nresidual core on photospectra by considering the neutral member with N=58 and\nand the ionic member with N=52 of the Na_58 iso-jellium series, where N is the\nnumber of valence electrons. A few final remarks on possible implications of\nthese results on other quantum systems of delocalized electrons are made.",
